50 tens = 50 x 10
50 x 10 = 500
your answer is 500

Solve this equation: $45 - ($2.75/pen)x = $12. Simplifying, we get
$33 = ($2.75)x, so that
x = $33 / ($2.75) = 12.
Tim's buying 12 pens leaves him with $12.
85/15 is 5 2/3
so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.
12*5 2/3=68.
you could also find it using the 1% method:
1% of 15 is .15.
.15*85=68.
Hope this helps!
An arc is a portion of the circumference which is 2pr. And you want the difference between the large and small arcs..
a=2pr(120/360) (we are multiplying the circumference by a fraction of the angle vs a complete circle...)
And the difference we seek is between the large and small arcs so:
d=(2p/3)(R-r)
d=(2p/3)(5-4)
d=2p/3 cm
d≈2.1 cm (to nearest tenth of a centimeter)
Area of a rectangle is lxb
(4x-3) * (2x+6) = 500
{(4x * 2x) + (4x * 6)} + {( -3 * 2x) + (-3 * 6)} - multiplying the factors
{8x^2 + 24x} + {-6x + -18}
8x^2 + 24x -6x -18 - removing the brackets
8x^2 +15x -18
Hope you found the answer helpful
